Abstract
A room air conditioner includes an air inlet, an air outlet, a heat exchanger disposed between the inlet and outlet, and an air circulation fan. The inlet is opened and closed by motor-driven inlet vanes. The outlet is opened and closed by a vertically slidable motor-driven door. Air direction control vanes extend across the outlet for varying the direction of discharged air. Before the door is either opened or closed, the air control vanes are automatically swung upwardly to a clearance position to avoid interfering with movement of the door. When the inlet and outlet are to be closed, the inlet vane motor is actuated prior the door motor to ensure that the inlet and outlet are fully closed simultaneously, even though it takes longer for the inlet vanes to travel to their fully closed state. A sensor determines when the door reaches an almost-closed state, and the door motor continues to operate for a set period thereafter to ensure that the door becomes fully closed.

The operation of ON/OFF control device is described now.
Fig. 9 A is the flow chart that is used to illustrate the ON/OFF control operating procedure of air conditioner of the present invention to 9D, and the label symbol S among the figure refers to method step.
For describing running, suppose that as original state suction inlet 3 and air exit 7 are closed.
At first, when electric energy adds to air conditioner, supply unit 100 converts the business exchange voltage from AC power terminal 101 to and drives the needed predetermined DC voltage of air-conditioner, exports same voltage afterwards to corresponding driving circuit and control device 104.
At step S1, receive from the DC voltage controlled device 104 of supply unit 100 output, and initialization air conditioner thus.
At this moment, when the expectation operational mode (automatically, cool off, dehumidify, dry, heat and other) of user by the operated key selection of operation device 102, be transfused to the temperature T s that sets, and when the operation key was pressed, an operation selected a signal and an operation commencing signal (hereinafter claiming run signal) to be input to the control device 104 from operation key control device 102.
In turn, at step S2, whether control device identification run signal is from 102 inputs of operation device, if there is not signal input (situation of No), air conditioner keeps an operation wait state and repeated execution of steps 2.
Result as step S2 identification, if run signal is transfused to (situation of Yes), then carry out step S3, driving pulse of control device 104 outputs is swung horizontal air to regulon 118 and upwards (is for example flowed to blade 9,10 °) to a headroom position, like this, air exit door 13 can be opened glibly and do not had stopping of blade 9.
Regulon 118 receives the driving pulse that comes from control device and comes drive motors 119, and it makes one group of moving part co-operating when rotating, and synchronously upwards swings horizontal blade 9.
At step S4, a calculator of control device 104 calculates the pulse output number in drive motors 119 processes, and this number of times and a reference value are come relatively to determine whether blade 9 has moved up 10 °.
A result as step S4 identification, if blade 9 is not upwards swung 10 ° (situations of No), operational process turns back to step S3, and control device 104 produces driving pulse and moved up 10 ° to regulon 118 up to blade 9, the step that reruns then S3.
A result as step S4 identification, if blade has moved up 10 ° (situations of Yes), follow execution in step S5, regulon 118 receives from the driving pulse of control device 104 outputs and stops motor 119, and interrupts the operation that moves up of blade 9 thus.
In turn, at step S6, control device 104 is opened pent suction inlet 3 by the control signal of a high level of an outlet terminal P1 output to suction inlet ON/OFF drive unit 112.
Convert low level from the control signal of the high level of the outlet terminal PI of control device 104 output to by converter IC113, rely on a DC voltage (12V) of supply unit 100 outputs, relay R YI is driven, and therefore closed contact R YIC.
Step S7, when the contact R YIC of relay R YI is closed, alternating voltage from AC power terminal 101 is applied on the coil 31a of suction inlet motor 31, drive suction inlet motor 31 forward rotation thus, and the pinion 32 that is connected of an axle of rotation and suction inlet motor 31.
Raised with the slide mechanism 33 of pinion 32 engagements, skewed slot 33a is also raised simultaneously.
The protruding 34b of blade 34 is owing to the rise of groove 33a is rotated, and guided by groove 35b.
Each blade 34 turns over a predetermined angle around its hinge axis 34a and opens suction inlet 3.
At step S8, control device 104 calculates the driving time of suction inlet motors 31, determine a preset time section (as, about 1 minute) whether use up, if the preset time section is not used up (situation of No), then return step S7 and continue to drive suction inlet motor 31.
A result as step S8 identification if the preset time section is used up (situation of Yes), then carries out step S9, and control device 104 produces a control signal to door motor drive unit 108, opens pent air exit 7.
In turn, door motor drive unit 108 drives air exit motor 21 according to the control of control device 104, and drives air exit motor forward rotation thus.
Move down tooth bar 25 with axle 22 gears that are connected 23 of air exit motor 21, the air exit door 13 that is connected with tooth bar 25 is opened air exit 7.
The time period of opening suction grille 34 ' required (for example, about 11.5 seconds) than (for example opening the required time period of air exit door 13, about 10.5 seconds) grow up about 1 second, like this, according to the present invention, with open suction grille 34 ' the driving starting point of suction inlet motor 31 set than the starting point of the air exit motor 21 of opening air exit door 13 Zao 1 second, can avoid the consumer to open the continuation of back suction grille 34 ' still like this and move the complaint that produces because of air exit door 13.That is, suction grille 34 ' unlatching moment of finishing be exactly that air exit door 13 is opened and finished constantly.
Go down successively, at step S10, discharge outlet portal 13 and surveyed by door open-close sniffer 110, and slide mechanism 33 is surveyed by suction inlet unlatching sniffer 114 by the raised position that 31 controls of suction inlet motor move up by the position that 21 drivings of air exit motor move down.
Now, control device 104 determines by receiving the signal that is detected by air exit ON/OFF sniffer 110 and suction inlet unlatching sniffer 114 whether air exit door 13 and suction grille are opened, if door 13 and grid 34 ' (situation of No) is not opened, then carry out step S10, continue to drive air exit motor 21 and suction inlet motor 31 up to door 13 and grid 34 ' be unlocked.
A result who distinguishes as step S10, if door 13 and grid 34 ' (situation of Yes) is unlocked, then proceed to step S11, air exit ON/OFF drive unit 108 stops air exit motor 21 according to the control of control 104, to stop the open operation of air exit door 13.
Suction inlet ON/OFF drive unit 112 stops to drive suction inlet motor 31 according to the low level control signal of the outlet terminal PI of control device 104 output, and stop thus suction grille 34 ' open operation.
When air exit door 13 and suction grille 34 ' by complete opening, step S12 control device 104 produce a driving pulse to vertical air direction regulon 118 to lower swing horizontal blade 9, like this, the Accurate Position Control of executive level ground sheet 9 operation initial point just can be fixed.
In turn, regulon 118 receives from a driving pulse of control device 104 outputs and comes drive motors 119, and such one group of connector 29 moves with matching, moves down horizontal blade 9 synchronously.
At step S13, control device calculates the pulse number of exporting in the motor 119 driving processes, and determines thus whether horizontal blade 9 reaches an initial starting position.
A result as step S13 identification, if horizontal blade 9 does not reach initial starting position (situation of No), operational process turns back to step S12, and control device 104 reaches initial starting position to regulon 118 output driving pulses up to blade 9, and follows repeating step S12.
Therebetween, a result as step S13 identification, if blade 9 has reached initial starting position (situation of Yes), then carry out step S14, control device 104 produces a driving pulse to regulon 118 blade 9 that moves up, and blade 9 just can be positioned in a vertical center like this, promptly, be horizontally disposed with, towards the front of air conditioner.
That is to say that regulon 118 receives from the driving pulse of control device 104 and comes drive motors 119, and one group of connector 29 is moved with matching, one group of horizontal blade 9 synchronously moves up.
At this moment, at step S15, control device 104 calculates the output pulse number when horizontal gas flow direction motor 119 is driven, and determines thus whether blade 9 arrives the central horizontal position.
As a result of step S15 identification, if blade 9 is not positioned at center (situation of No), operational process turns back to step S14, control device 104 output driving pulses to regulon 118 till blade 9 reaches the center.
Therebetween, a result as step S15 identification if blade 9 reaches center (situation of Yes), then carries out step S16, regulon 118 receives the driving pulse that sends from control device 104 and stops motor 119, stops the Position Control operation of horizontal blade 9 thus.
In turn, at step S17, control device 104 sends a driving pulse and comes 11 to centers of mobile vertical vane to horizontal gas flow direction regulon 120.
Regulon 120 receives the driving pulse that sends from control device 104 and comes drive motors 121, and one group of blade 11 is moved to the center simultaneously, and promptly blade is positioned on the plane vertical with the air outlet slit plane.
At step S18, the pulse number that control device 104 sends when calculating motor 121 work, and whether definite vertical vane 11 is positioned in the center.
A result as step S18 identification, if blade 11 is not positioned at center (situation of No), operational process turns back to step S17, and control device 104 sends driving pulse to regulon 120, till blade 11 is positioned at the center, and the step S17 that then reruns.
Therebetween, a result who distinguishes as step S18, if blade 11 is positioned at center (situation of Yes), then carry out step S19, regulon 120 receives the driving pulse that sends from control device 104 and stops motor 121 to finish the Position Control operation of blade 11.Like this, blade 9,11 is just discharged air with an initial position perpendicular to the direction forward of pelvic outlet plane.
In turn, at step S20, blower motor drive unit 124 comes the rotating speed of control room inner blower motor 39 with drive chamber's inner blower 41 according to the control of control device 104.
When indoor fan 41 was driven, room air began to be drawn in the body 1 from suction inlet 3, and simultaneously, the temperature T r of the room air that is inhaled into from suction inlet 3 is surveyed by indoor temperature sniffer 106.
At step S21, between the temperature T s that indoor temperature Tr that indoor temperature sniffer 106 detects and user set by operation device 102, do a comparison, determine whether to answer drive compression machine 123 thus.
A driving condition of compressor 123 means, under the situation of cooling operation, the temperature T s height that the indoor temperature Tr that indoor temperature sniffer 106 detects sets than the user, and under the situation of heating operation, the indoor temperature Tr that indoor temperature sniffer 106 detects is lower than the temperature T s that the user sets.
A result as step S21 identification, if compressor 123 does not need to be driven (situation of No), operational process turns back to step S20, indoor temperature Tr continues to be detected, the step that then reruns S20, if compressor 123 requires to be driven (situation of Yes), then carry out step S22, control device 104 is handled the running frequency of compressor 123 as the function of the difference between indoor temperature Tr and the design temperature Ts, and issues 122 1 control signals of compressor drive apparatus and come drive compression machine 123.
Then, the running frequency drive compression machine 123 determined according to control device 104 of compressor drive apparatus 122.
When compressor 123 was driven, indoor fan 41 was driven in step 23, and room air is inhaled in the body 1 by suction inlet 3, and the room air that is inhaled into by suction inlet 3 is heated by heat exchanger 37 or cools off.
After upwards leaving heat exchanger 37, air upwards flows and is drained into indoor with the determined direction of the deflection of horizontal blade 9 and vertical vane 11.
